10 cups


  • 2 tablespoon olive oil

  • 3 medium zucchini, halved lengthwise and sliced 1/4-inch thick

  • Nonstick cooking spray

  • 6 cup bite-size cubes garlic focaccia bread

  • 1 ¼ cup shredded provolone cheese (5 oz.)

  • ½ cup grated Parmesan cheese

  • ¼ cup chopped roasted red bell peppers

  • 2 tablespoon snipped fresh Italian parsley

  • 2 tablespoon chopped fresh basil

  • 6 eggs, lightly beaten

  • 2 cup milk

  • ½ teaspoon salt

  • ½ teaspoon black pepper


  1. Preheat oven to 350°F. In a 4- to 5-qt. Dutch oven heat oil over medium-high heat. Cook zucchini, half at a time, in hot oil until lightly browned, stirring occasionally. Transfer to a large bowl; let cool slightly. Wipe out Dutch oven with paper towels (or wash and dry, if necessary). Coat with nonstick cooking spray.

  2. Stir the next six ingredients (through basil) into zucchini. Spoon mixture into the Dutch oven. In the same bowl combine the next four ingredients (through black pepper); pour over bread mixture in pot. Using the back of a large spoon, press lightly to moisten bread completely.

  3. Cover and bake 45 minutes (for a 5-qt. pot) to 60 minutes (for a 4-qt. pot) or until a knife inserted in the center comes out clean. Let stand, covered, 15 to 20 minutes before serving.

Make-Ahead Tip:

The dry ingredients and wet ingredients can be prepped ahead of time and refrigerated separately up to 24 hours. On serving day, pour the egg mixture over bread mixture. Continue as directed in Step 3.

Is It Done?

To check an egg casserole for doneness, insert a knife in the center toward the bottom of the pot. If the knife comes out clean, it's good to go. If you see some liquid on the knife (or on the surface of the casserole), pop it back into the oven for 5 to 10 minutes longer.
